Impact of dynamical chiral symmetry breaking on meson structure and interactions

Abstract

We provide a glimpse of recent progress in meson physics made via QCD's Dyson-Schwinger equations with: a perspective on confinement and dynamical chiral symmetry breaking (DCSB); a pre'cis on the physics of in-hadron condensates; results for the masses of the π, σ, ρ, a_1 mesons and their first-radial excitations; and an illustration of the impact of DCSB on the pion form factor.
